What Are Whole House Water Filters?

Basically, whole house water filters are filtration systems that treat your water at the point of entry into the house — usually next to the main water shutoff.

These filtration systems remove all contaminants such as excess chlorine, sand, minerals, bad odors like sulfur, bad tastes, acidic substances, and heavy metals like lead and nickel.

According to the Centers for Disease Control and Prevention, you need to choose a water filter when:

  • You don’t like the taste of your water
  • You are worried that there are heavy, hazardous metals in your water
  • There are nitrates and chlorine compounds in your water
  • You have a poor immune system
  • Your water is hard (and may damage copper piping)
  • You need you pure water for religious rites

Whole home water filtration systems are designed in such a way that after water is passed through them, ALL of the home’s faucets are good for drinking, showering, and general usage.

The PennState Extension asserted that most unhealthy substances, odor and taste in water can be treated with a whole house water filter if properly maintained.

What Are The Benefits Of A Whole House Water Filtration System?

Before any homeowner decides to install a whole house water filter, it is good to know some of the benefits that can come with using one. These benefits include the following…

  • Elimination of chlorine: Although chlorine at a minimal level is used to kill the bacteria present in water, excess chlorine in drinking water leads to illnesses. When you take a shower, lead is put into the air, and you actually breath it in. Chlorine also doesn’t give the best taste to water if you catch my drift.
  • Elimination of hardness in water: It is known that the use of hard water is not healthy for your skin, your health, or your pipes. Advanced whole house water filters can act similarly to water softening systems and will reduce minerals in your water — making it healthy when in contact with your skin or easy to form lather when washing clothes. Having less minerals in your water such as calcium will also help your appliances run more efficiently and extend their lifetime.
  • Removal of debris and dirt: Often times seeing dirt or particles in water is irritating to most people even if the water is safe for drinking. Installing a whole house water filter ensures that particles or dirt are removed from the water right from the main source.
  • Removing bacteria and parasites: A whole house water filter will remove microscopic organisms that may be present in well or municipal water. If a sewer line breaks in your neighborhood, there is a chance that it will contaminate the water supply. A house water filter can give you peace of mind.
  • Odors and smells: A whole house water filter can minimize or eliminate off smells such as sulfur from your water as a result of chlorine, lead, and other chemicals.
  • Minimizing lead: Lead is a scary word, and we have all heard of the fiasco in Flint Michigan where there has been extensive lead water contamination. But even acceptable levels of lead in municipal water isn’t acceptable to many people. A whole house water filter will greatly reduce the amount of lead in your water.

How to Install a Whole House Water Filter?

To enjoy your whole house water filtration system, you will need to install it properly. The installation of a water filter often requires some plumbing skill. However, a homeowner with some DIY skill may wish to save the cost of hiring a plumber.

Another option is to buy a whole house filter yourself, and then hire a plumber to just install the part — this is usually the best way to save money (and have it professionally installed).

As a simplified and quick overview, here are the main steps to install your whole house water filter system…

Step 1: Find the right location for your water filter. It is often preferable to select a place where the main water line enters your home. This ensures that filtered water flows through every other faucet in your home. The main location should be a place that is easily accessible because the filter will eventually need to be changed.

Step 2: Shut off the main water supply

Step 3: Open all faucets and fixtures to drain all the water left in the pipe lines.

Step 4: Remove a section of your pipe which will be replaced with your filter system.

Step 5: To make it easy to maintain or replace your whole house water filter, install a shut-off valve so that you have two shutoffs on both sides of the system. You can also install a bypass valve so that during the maintenance of your whole house water filter, water can still run through your home.

Step 6: Install a pressure gauge next to the shut-off valve so that you can always check the pressure level of your water; and so you can know when it is time to change the filter.

Step 7: Fit the existing plumbing pipe into the whole house water filter system. If the pipe size doesn’t fit the whole house water filter, consider using adapter fittings. Then seal all the threaded ends using Teflon tape. This will help prevent leakages. You may also need to solder the joint. But if you use push fittings, you may not need to.

Step 8: Rinse all the housings that come with the whole house water filter with warm water. This will help remove all particles or contaminants that come with the filter from the manufacturer. Then, apply grease on the O-rings and ensure that they are positioned tightly.

How To Pick The Best Whole House Water Filter?

Before you purchase a whole house water filter, there are certain things you will need to consider in order to select the best one. Things like…

  • Home suitability: For instance, if your water is provided by municipal services, then your water might be susceptible to contaminants such as sediments, chlorine, minerals, and chemicals. But if your water source is from a private well, then the water will probably be susceptible to hardness, minerals, iron and other toxic substances. So you select the water filter that is capable of removing the likely contaminants from your water source.
  • Flow rate of the filtration: Before you purchase a whole house water filter, it is essential to know the flow rate of the filter. The flow rate is the amount of water that can run through the water filter per time (in minutes). And the flow rate of your filter will determine the amount of water you get from the water filter per minute. Therefore, you should pick a water filter that dispenses as much water within the shortest time possible without compromising filtration.
  • Size of the filter: There are various sizes of whole house water filters available. A large filter can service high water supply and have a long service life. Nevertheless, you will need to know the location of your water filter before considering the size.
  • NSF certification: Great whole house water filters are certified by NSF. This is because they comply with quality standards and specifications.

How Are Whole House Water Filters Different From Other Types Of Filtration Systems?

It was reported by North Dakota State University that the major home filtration products are sediment filters, activated carbon filters, and mixed media.

Most home water filters employ one or a combination of the these filters and they are mostly used because of their efficiency and range of use when compared to other types of filter.

For instance, while reverse osmosis, one of the most widely used filtration systems, is convenient and effective for water filtration, it is used only at the point of use, specifically under the sink.

This means that every other source of water in the house is not filtered. Also, it is more costly to have the reverse osmosis filtration systems installed at every nook of your house than having a single filtration system.

Apart from the points mentioned above, whole house water filtration systems have high flow rates (thousands of gallons of water per day). In general, a whole house water filter reduces cost, is easy to maintain, and has lower maintenance.

Where To Buy The Best Whole House Water Filter?

There are many outlets—both online and offline—that sell whole house water filters. However, it is important that when you want to buy your water filter, you should look for a place that sells quality whole house water filters.

In my opinion, Amazon is a great market to find a whole house water filter because you can choose from a variety of products, and read an extensive amount of customer reviews.

Amazon also has a great return policy, and shipping is usually very fast…sometimes free.
